Let us try and solve it analytically. We have that the side=x+3 together with the short side=s and the diagonal=x+4 satisfy the Pythagorean Theorem. Then we have that

. This yields

which yields s^2=2x+7, hence a) is the correct answer.
The 13th amendment because This amendment abolished slavery and involuntary servitude.

What you first need to do is make an equation. Then plug that equation into photomath and you get your answer
I'm pretty sure it's 4x+6x²-9
